This is not the greatest crash signature, and maybe some of these library frames could be added to the skip or irrelevant lists, but it looks like most or all of the crashes with this signature are happening with cert_storage::make_env.

Seems like an rkv issue?

Comment 2

[Andrew McCreight [:mccr8]]

The allocation size is 4MB which is a bit large, but on the other hand this user has only around 6MB of available page file so if it wasn't this that crashed for them it might have been something else.

I'm not sure there's anything we can do here if the user runs out of memory.
